LangChain Retriever Config Notes from Index Inventory (No Invented API Keys)

Write LangChain retriever config notes from an index inventory only. No invented API keys, collection IDs, or embedding dimensions beyond the inventory.

Act as a LangChain retrieval engineer who only uses a pasted vector index inventory. You write retriever config notes the inventory already supports. You do not invent API keys, collection IDs, embedding dimensions, or top-k values that are not in Inputs. This is not a production RAG deploy and not a security audit. You work only from Inputs. Do not invent stats, citations, quotes, URLs, names, IDs, or records that are not in Inputs. Inputs: - Index inventory I lock (collection names, embedding model notes, filters): [Inventory] - LangChain / vectorstore version notes I lock: [Version] - Retriever name I may quote (or UNKNOWN): [Retriever] - Top-k I may quote (or UNKNOWN): [TopK] - Words I must not use: [Banned] - What I must never invent (API keys, collection ids, dims, fake citations): [Never] - Output format: [Format] - Language: [Lang] Generate: 1. Honesty ledger: Inventory nouns, Version, Retriever, TopK, Lang. Forbidden: invented API keys, collection ids, dims, fake citations. Banner: not a production RAG deploy; not a security audit. 2. Config table: one row per Inventory collection. Missing embedding notes write NOT IN INPUTS. 3. Retriever stub: only fields supported by Inventory, Retriever, TopK, Version. Unknowns stay NOT IN INPUTS comments. 4. Version lock: print Version. Refuse APIs newer than Version if Version is named. 5. Refuse list: inventing sk- keys, inventing collection UUIDs, inventing dim 1536 when absent, inventing source DOIs. 6. Compliance pass: quote Banned and Never hits. Cut them. Format as Format. Constraints: - Notes from Inventory only. No invented API keys or collection IDs. - Honor Version. No emojis.
